The 2 most popular are probably XEmacs and VIM (in GUI mode). Both of these editors have advanced features like syntax highlighting, the ability to make/compile the code, etc. You can also find a number of GUI-based text editors ala MS Word: Corel's WordPerfect, Applixware (office suite), StarOffice, etc. The Linux Applications page (www.xnet.com/~blatura/linapp6.html) lists a number of editors.
